Additional Details

The APM Hexseal APM6991 typically consists of a metal body (often stainless steel or other corrosion-resistant alloy) with a molded-in rubber sealing element. The rubber element is designed to compress and fill the gap between the fastener and the mating surface, creating a reliable seal. These fasteners are available in various sizes and materials to suit different applications and environments. Proper installation is crucial to ensure the effectiveness of the seal. Torque specifications should be followed to achieve the correct compression of the sealing element.
